HYDRO-MECHANICAL DEEP-DRAWING
using the following processes:
- EHF: external high-pressure forming
- IHF: internal high-pressure forming
SAMPLE APPLICATIONS
- Complicated geometries
- Widened pipes
- Intersections in the design
- Parts with high surface quality
- Parts consisting of multi-layer sheet metals
- Prototype production
- Small and medium-sized batch production
ADVANTAGES
- Complicated geometries can be produced
- High surface qualities
- Lower tool costs compared with traditional methods
- Drawing ratios of up to over 4.2 possible
- Complicated parts in one drawing process
- Little or no lubrication
- No drawing beads and drawing traces
- Source material for the deep-drawing parts can be coated, painted or polished
TOOL ADVANTAGES
- Flexible range of use
- Lower capital outlay costs
- Rapid production times, as tools are not hardened
- Due to coating of working surfaces, highly complex parts can be produced
- Long service life of tools
